I just bought a new SD Tivo off Ebay to replace one I already had becouse one of the tuners went bad. My question is, will I be able to use the access card from my old Tivo to activate the new one or the one that is coming with the new tivo, or will DirectTV want to send me a new card? If they do insist on sending me a new card can I get them to ship it to my billing address instead of my service address? My other question is will DirectTV give me any trouble adding a 7th receiver to my account? Thanks people.
